These rapid changes in the direction of flow of the vapors causesany liquid entrained therein to be thrown out and to collect in the l0\er portion of the saveall on either side of the partition 5, from whichthe collected liquid may be returned to the evaporator by the dischargeconnections, as described. The purpose of the screen 7 is to break upany bubble formation of the entrained liquid, thereby to facilitate theseparation of the liquid from the vapors.

\Vhat I claim is:

1. A saveall comprising a drum having inlet and outlet openings in itsends, a transverse partition secured to its inner wall ant having a.central opening, baflle plates on each side of the partition, and aseries of curved vanes disposed between th faces of the partition andthe respective battle plates.

2. A saveall comprising a drum having inlet and outlet openings in itsends, a transverse partition secured to its inner wall and having acentral opening, baiile plates on each side of the partition of largerarea than the opening in the partition, and series of arcuate vanesdisposed between the faces of the partition and the respective battleplates.

3. A saveall comprising a drum having inlet and outlet openings in itsends, a transverse partition secured to its inner wall and having acentral opening, baiiie plates on each side of the partition of largerarea than the opening in the partition, and a series of arcuate vanesdisposed between the faces of the partition and the respective battleplates, the vanes of the respective series being curved in oppositedirections.

t. A saveall comprising a drum having inlet and outlet openings in itsends, a transverse partition secured to its inner wall and having acentral openin baflle plates on each side of the partition, a series ofcurved vanes disposed between the faces of the partition and therespective bathe plates, and cylindrical screen engaging the peripheryof the opening and abutting the inner faces of the b'aflle plates.

5. A saveall comprisinga drum having inlet and outlet openings in itsends, a transverse partition secured to its inner wall and having acentral opening, baille plates on each side of the partition of largerarea than the opening in the partition, a series of arcuate vanesdisposed between the faces of the partition and the respective baflle pfates, and a cylindrical screen engaging the periphery of the opening andabutting the in; 21' faces of the baiiie plates.

6. A saveall comprising a drur having in let and outlet openings in itsends, a transverse partition secured to its inner wall and having acentral opening, bafl'le plates on each side of the partition of largerarea than the opening in the partition, a series of arcuate vanesdisposed between the faces of the partition and the respective bailleplates, the vanes of the respective series being curved in oppositedirections, and a cylindrical screen engaging the periphery of theopening and abutting the inner faces of the bailie plates.

7. A saveall comprising a drum having inlet and outlet openings in itsends, a transverse partition secured to its inner wall and having acentral opening, baii'le plates on each side of the partition, a seriesof curved vanes disposed between the faces of the partition and therespective bafl'le plates, and drain connections from the bottom of thedrum on each side of the partition.

In testimony whereof I afiix my signature.
